Troubleshooting

The Raspberry Pi does not perform a safe automatic shutdown when a power failure occurs, the supercapacitors will be drained and the Raspberry Pi crashes.

shutdown_script file not installed properly on your Raspberry Pi

some other setting or some other software in the Raspberry Pi is blocking the communication at the signal pin GPIO25 (GPIO23 optional).

the signal pin GPIO25 (GPIO23 optional) is blocked by some other hardware connected to the GPIO port in the stack.

after a previous reboot command the automatic shutdown function will be disabled. Use our rebootj4h script file instead of any other standard reboot commands.

there is another power source supplying the Raspberry Pi backward (e.g. via the signal connections). Using the Micro-USB connector on the Raspberry Pi for power supplying is not allowed. The Juice4halt has no control over this power source.

When the Juice4halt module is removed from the Raspberry Pi, it will immediately shut down after booting.

This is a correct behavior, signaling that there is no connection between the Raspberry Pi and the Juice4halt module. For operating the Raspberry Pi without the Juice4halt module please deactivate or remove the shutdown_script file from the Raspberry Pi.
